Wheel cable mobile structure video frequency monitoring system

Abstract

The invention discloses a monitoring system of mobile type health video of a wheel cable, and can be used for monitoring the strain increment and corresponding deformation of injury, generation and development of cracks, designated points of the structure of all monitored parts of large-scale structures, such as bridges, houses, dams and so on, so as to further analyze the health of the structureand to warn the transfinite anomalies. The monitoring system comprises a wheel cable system which consists of a pulley and a cable, a traction power system which is used for driving the wheel cable system to operate, a shooting system which is fixed on the cable of the wheel cable system and is passively drawn, and a remote monitoring server which is arranged in a chamber; the shooting system is used for acquiring the video information of the tested structure through the moving wheel cable system according to instructions, and transmitting the information to the remote monitoring server; the remote monitoring server is used for comparative analysis and evaluation of the health status of the received information.

Description

technical field [0001] The invention relates to a cable mobile structural health video monitoring system, in particular to a cable mobile video system which can be used for short-distance and high-precision monitoring of bridges, dams and other structural health. Background technique [0002] Usually people will use the camera system to monitor the object that needs to be monitored, so as to know the situation of the object conveniently. However, if the scope of the surveillance object is huge, in order to implement global surveillance, it is necessary to set up a large number of cameras for surveillance. The installation of multiple cameras is likely to cause the problem of high monitoring costs. At the same time, when multiple cameras are used to implement global monitoring, only long-distance monitoring of the object under test can be implemented. For large objects in the field such as bridges, dams, and mountains, it is necessary to monitor the cracks, defects, relative...

Problems solved by technology

[0004]The structural health monitoring system used at home and abroad usually consists of various sensors installed on the structure to form structural information collection, information transmission, information reception, data analysis and health evaluation The existing problems are high cost, difficult maintenance, poor system stability, and difficult data analysis. It cannot give people a structural state that seeing is believing, and the credibility is not high.
